I just purchased 06 330xi and I can't seem to figure out if it has an anti theft device or not. When I exit the car and hit the lock button the lights blink but there isn't any chirp or horn or anything like that...I'm totally frustrated cause I looked it puny the VIN and it says it comes standard but I can't figure it out HELP me please!!!!

hope u have figured it out by now. but no alarm. it is pre wired for one if it has the red bulb thing under rearview mirror but you have to buy the rest of wiring. and alarm housing unit. (600.00). at BMW. for parts and installation.
